The system of equations has how many solutions? y=-3/2x+5 and y=-3/2x-3
a) 0
b) 2
c) 1
d) infinitely many

; )

step-by-step explanation: ; )

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
